INTRODUCTION
Thank you for purchasing a Furman Prestige Series Power Conditioner, and congratulations on your choice. The Prestige Series P-1800
PF R Power Conditioner features Furman's revolutionary Clear Tone Technology, transient Power Factor Technology, Series Multi-Stage
Protection (SMP) circuit, and our exclusive Ultra-Wide-Bandwidth Linear Filtering Technology (LiFT). Together, these technologies
comprise precisely what our customers have grown to expect from Furman: uncompromised protection and purification. The P-1800
PF R has been precisely engineered to more than meet the critical demands of recording studios, broadcast facilities, and discerning
musicians alike.
Unique to the Furman P-1800 PF R are Clear Tone and Power Factor Technologies, which were developed specifically to address the
needs of professional musicians. Whether playing in a stadium, bar, rehearsal space, or studio, every venue has one thing in common:
the AC power is supplied from the local utility. What's worse is that the power supplied from the building's AC outlet is typically poor,
thanks to increasingly over taxed power lines and raised line impedance. In fact, the quality of AC power has been so poor for so long,
most musicians have no idea how great their instrument amplifiers could really sound!
When the AC transient power factor is poor and the line impedance is high, amplifiers sound muddy because their power supplies sim-
ply can't deliver when pushed. The scream and cry from a guitar loses bite and harmonics, bass guitars lose their punch and weight,
keyboards sound nasal and lose clarity, attack, and extension.
Furman's P-1800 PF R addresses this issue - allowing instrument amplifiers and powered studio monitors to sound their best while of-
fering comprehensive protection at the same time.
DESCRIPTION
Power Factor Technology/Clear Tone Technology
The P-1800 PF R's Power Factor Technology actually lowers the AC line impedance supplied by your wall outlet, while storing energy
for peak current demands. In fact, there are over 45 amps of instantaneous peak current reserve in the Furman P-1800 PF R. Addition-
ally, with Clear Tone Technology, every nuance of your sound is revealed due to the exceptionally wide bandwidth of the P-1800 PF R's
linear filter! Most AC filters reduce substantial levels of noise, but typically in frequencies above audibility. The P-1800 PF R scrubs
the AC line noise in the range your instrument produces its harmonics and tone character. Whether you want squeaky clean, punchy,
stinging, or grunge, YOU control your sound - not your local AC tap!
SMP (Series Multi-Stage Protection) with EVS (Extreme Voltage Shutdown)
Furman's SMP (Series Multi-Stage Protection) surge suppression virtually eliminates service calls and costly "down time". Traditional
surge suppression circuits sacrifice themselves when exposed to multiple transient voltage spikes, requiring the dismantling of your
system, and repair of your surge suppressor. Not so with Furman's SMP. With SMP, damaging transient voltages are safely absorbed,
clamped, and dissipated. Your connected equipment is protected, while your Furman protects itself!
